OmniVision Technologies, Inc., a developer of advanced digital imaging solutions, has been awarded the Guinness World Record for “The Smallest Image Sensor Commercially Available” (0.575 mm × 0.575 mm).
In announcing the award at MD&M Minneapolis, the company also announced its OVM6948 CameraCubeChip—a fully packaged, wafer-level camera module measuring 0.65 mm × 0.65 mm, with a z-height of just 1.158 mm.
These medical imagers address the market demand for decreased invasiveness and deeper anatomical access. Additionally, they can address the many challenges posed by reusable medical imaging equipment, including cross-contamination risks and inefficiencies due to high maintenance costs.
Utilizing a wafer-level packaging technology, the OVM6948 is making the mass production of disposable medical imaging equipment possible. Additionally, this complete module can be integrated into a catheter or endoscope with a diameter as small as 1.0 mm. With this camera’s small size and high 200 × 200, or 40 KPixel backside-illuminated resolution, high quality images can be captured from within the body’s narrowest blood vessels for neuro, ophthalmic, ENT, cardiac, spinal, urology, gynecology and arthroscopy procedures. Additionally, many space constrained dental, veterinary and industrial applications can benefit from the OVM6948’s design.
The OVM6948 is an ultra-small “chip on tip” camera with backside illumination, which provides excellent image quality and better low-light performance to help reduce LED heat, along with improved sensitivity. It also allows for the use of superior lens technology over competing front-side illumination cameras in this class.
Other key features of this camera module include a wide 120-deg. field of view and an extended focus range of 3 mm to 30 mm. Its image array is capable of capturing 200 × 200 resolution images and video at up to 30 frames per second, and its analog output that can transmit over 4 meters with minimal noise. The camera also offers low power consumption of 25 mW.
The OVM6948 is available now for volume production in the tray format, along with an evaluation kit.
